Longpass Filters

Our Longpass Filters pass longer red and Near-Infrared (NIR) wavelengths while blocking UV-blue energy to protect sensors from degradation and preserve accurate skin tones. This makes them vital for technical systems like NIR fluorescence detection and drone-based imaging. In entertainment and architecture, they serve as a permanent, reusable alternative to disposable gels, generating warm amber or sunset-red color washes.

Built with a durable coating on your choice of high-performance glass, every filter is heat-resistant and certified to the rigorous MIL-M-13508C standard for reliability. We produce any size or shape, from 10 mm discs to 300 x 300 mm panels, and offer advanced customization like shifted cut-offs, dual-band versions, or rugged over-coats to create exactly what you need.
